Olesya once had everything: music, a bright future, and love. But in an instant, life ended, and only fear remained. Sasha's familiar world collapsed after his grandfather was hospitalized. Now the whole meaning of his life has narrowed down to one goal — to do everything so that his beloved grandfather gets better, which means, by all means, to find the unknown Tosya, for some reason very important to his grandfather, a woman from the past. Fate will push these heroes together, closely intertwine their paths and turn everything in its own way: it will turn losses into gains, and helplessness into strength.Giving answers to the riddles of the past and freeing the characters from their fears, Roy gracefully weaves reflections on many painful topics into the narrative: betrayal, permissiveness and disenfranchisement, domestic violence, the learned helplessness of victims and the impunity of tyrants.Non—trivial plot twists, deeply researched characters, and lively, imaginative language are the hallmarks of Roy's prose, which is read by people of all generations. "I'm Sorry" is his typical novel that leaves a long aftertaste.
